Referring now to the means D used for connecting the cylinder 7 to thechannel beam of the chassis, the same consists of sleeves 9 surroundingthe cyhnder, and

which are preferably disposed adjacent to each end of the cylinder.These sleeves 9 are provided, with, attaching brackets or plates 10 and1-1, which can either be riveted, bolted, or otherwise secured to theside beams 5 of the chassis. These sleeves 9, can be secured to thecylinder in any preferred manner, and as shown, set screws 12 areprovided for this purpose, and which screws may extend entirely throughthe sleeves and into the cylinder as clearly illustrated in Figures 2and '4.

.The plungers E and F which are of identical construction, and which aremounted at each end of the cylinder 7, include heads 13 and stems orrods 14 which extend through the bearings 8 and project outwardly fromthe opposite ends of the cylinder 7. The terminals of the rods or stems14 are pivotally connected to the shock distributing levers G bymeans'of pivot pins 15.

The supporting and shock distributing 1evers G, which are of identicalconstruction, are disposed on opposite sides of the transverse center ofthe cylinder 7, and have their inner ends reduced in width to providelugs 16, while them-outer ends are provided with upwardly extendingsubstantially right angularly'disposed ears 17. These ears 17 areadapted to embrace the opposite sides of the rods 14 adjacent the outerends thereof, and these ears 17 can be provided with openings for thereception of the pivot pins 15.

Referring now to the means H for operatively connecting the shockdistributing levers Gr together and to the axle of the vehicle, the sameconsists of blocks 18 having their opposite terminals bifurcated toprovide ears 19 between which the lugs 16 formed on the inner ends ofthe levers G are adapted to fit. These ears 19 and the lugs 16 can beprovided with aligned openings for the reception of pivot pins 20. Thecentral portion of the blocks 18 at tholongitudinal axis thereof, can beprovided with vertical openings 21, and these openings 21 are adapted toreceive the shank portions of shackles 22, which can be extended aroundthe axle of the vehicles, for effectively connecting the shockdistributing levers Gr with said axle. It will be apparent that theblock 18 and shackle 22 may be dispensed with, if so desired, by formingears upon the axle for pivotal mounting of the inner ends of th shockdistributing levers. I

' Theshock absorbing means I, consists of helical expansion springs 23,which are coiled about the rods 14, with one end thereof bearing againstthe plunger head 13, and with the opposite end bearing against the guide8. These expansion springs 23, and as is readily apparent, normally urgethe plunwill be forced upwardly in a vertical path,

thus tending to force apart the arms G, and which will in turn drawoutwardly on the plungers E thus tending to compress the expansionsprings 23. Thus the springs 23 will check the travel of the outwardmovement of the plungers E and F for effectively absorbing a shockdelivered to the block 18. When the plungers E and F tend to resumetheir normal position, the heads 13 thereof will act against the spring24, in a manner for effectively checking the inward travel of theplungers and thus prevent any rebound.

From the foregoing description, it can be seen that an exceptionallysimple spring suspension for vehicles has been provided, in which theuse of leaf springs is entirely eliminated, and in which the shock andrebound is entirely taken care of by. helical springs which istransmitted thereto by novel shock distributing levers which areconnected to the vehicle axle.

Changes in detail may be made to the specific form of the inventionherein shown and described, without departing from the spirit of theinvention or the scope of the claim.

.I claim I11 a motor vehicle, the combination with the chassis thereofincluding a frame and axle, of resilient suspension means for connectingthe frame and axle, said suspension means comprising, a cylinder,pistons in said cylinder and rods for said pistons extending in oppositedirections out of the cylinder,

end bearings in the cylinder, guiding said piston. rods, a coil springbetween said pistons, a coil spring for each piston disposed between itand its respective end bearing,

sleeves secured to the chassis frame and emthe axle.
